Attendant chucked waste on road (7)
I believe the answer is:
steward
'attendant' is the definition.
(I know that steward is a type of attendant)
'chucked waste on road' is the wordplay.
'chucked' is an anagram indicator (letters chucked around).
'on' means one lot of letters go next to another.
'road' becomes 'rd' (abbreviation).
'waste' is an anagram of 'stewa'.
'stewa'+'rd'='STEWARD'
(Other definitions for steward that I've seen before include "Overseer" , "Official at function" , "Aircraft attendant" , "Attendant on ship - race official" , "Horse-racing official" .)
